The rate/duration reading of the bundle header came from the values alone, so it was checked against something the file states independently: the keyframe `time` fields in the placement region. Over the 2313 bundles that have both, the largest keyframe time is <= +0x08 in EVERY one, none exceeds it, and 444 reach it exactly. The refutation attempt is in the same data: a large unrelated constant would bound every time too, but the max_time/+0x08 ratio would then pile up near zero - instead it peaks at exactly 1.0 with 520 bundles. Asserted, including the shape of that histogram, so the bound cannot later be waved through as vacuous. Stated precisely because the units are a separate claim: what is proven is that +0x08 is the animation length in the SAME UNIT as a keyframe's time. That the unit is frames still rests on the values (30/60/120/1200) and on the 16.16 reading of +0x04, which stays amber - the only new evidence for it is that the twelve 30.0 bundles cap at +0x08 = 30 while the 2843 60.0 ones reach 1440, and twelve bundles is not a demonstration.
